i didn’t mean to jump down your throat. I’d trust a collegiate coach any day over “self proclaimed expert out of his own warehouse”…
but then again, you still get guys like jeremy maclin who trained with his collegiate coach specifically for the 40 yard dash for 4 months or so… but then ran terrible at the combine. We both saw that video someone posted on here… a bunch of “new technology!” BS that doesnt work.
Best to stick to a training method like charlie’s and worry about peaking at the right time rather than crazy crash training trying to take .2 off your 40 in 4 months.
